Analog Devices Inc. (ADI), maker of the Blackfin CPU and a wide variety of input and output devices targeted at embedded system designers, has put together a white paper for its customers to help them understand free and open source software (FOSS). While it uses examples specific to ADI devices, it would be useful to many embedded developers who are trying to wrap their heads around FOSS. "The popularity of FOSS in the embedded markets is dominated by simple economic motivation—it lowers software costs and hastens time to market. It turns "roll-your-own" developers into system-level integrators who can focus on adding value and differentiating features of their products rather than reproducing the same base infrastructure over and over again. It is the only proven methodology to reel in out-of-control software development costs."
